WINDOW-GUARD.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed October 28, 1916. Serial No. 128,164.

To all whom it may concern:

Be it known that I, CHARLES E. PEARSON, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in l/Vindow-Guards, ofwhich the following is a specification.

My invention relates to window guards and particularly to guards whichare adapted to be secured to the frame sill and to the sash to followthe sash when opened and to guard the opening against outsiders.

Among the important objects of the invention are to provide improvedmeans whereby the occupant may readily attach the guard to the framesill and to the sash; to provide improved means for preventmg tamperingwith or detachment of the securing and locking means; and to provide1mproved means adapted to be secured to the frame top and to the uppersash to limit the opening distance of the upper sash and to guard theopening after such sash has been lowered.

On the accompanying drawings guard mechanism is shown in which thefeatures of my invention are embodied.

On the drawings Figure 1 is an elevational view of a window frame andsash with my guard mechanisms applied thereto.

Fig. 2 is an enlarged sectional view on plane 2-2, Fig. 1,

Fig. 3 is an enlarged sectional view on plane 3-3, Fig. 1,

Fig. 4 is an enlarged sectional view on plane 44, Fig. 1, and

Fig. 5 is an enlarged sectional view on plane 5-5, Fig. 1.

On the drawing 10 represents the sill and 11 the top of the window frameF, and 12 and 13 represent the upper and lower w1ndow sashes providedwith panes 14 and 15.

Thewindow guard for the lower sash comprises upper and lower horizontalbars 16 and 17 and intermediate horizontal bars 18. The intermediatebars are secured to adja cent inner pivots 19 of lazy tong structures20. The lower links 21 and 22 of the outer lazy tong structures arepivoted to. the upper ends of L-shaped latch members 23 whose lower ends24 are deflected inwardly,

and at intermediate points these latch mem bers are secured to the lowerhorizontal bar 17 The lower links of the intermediate lazy tongstructures are pivoted to pieces 25 which are also secured to the bar17. The upper links of the lazy tong structures are pivoted to pieces 26which are secured to the upper horizontal bar 16.

For receiving the ends 24 of the latch members 23 rectangular plates 27are provided and adapted to be secured to the sill by screws 28. Thecentral sections of the plates are deflected upwardly to form loops 29for receiving the ends 24, as best shown in Fig. 3. By tilting the guardinwardly the ends 24 can readily be inserted through the loops. Theupper'bar 16 has slots 30 at its ends for receiving the horizontal endsof angle pieces 31 secured to the lower window sash. \Vhen thussupported the guard will expand as the lower sash is raised and willguard the opening, and the guard will contract when the sash is lowered.In order to lock the bar 16 to the fittings 31 hasp levers 32 arepivoted to the bar 16 preferably by the same rivets 33 which secure thepieces 26 to the bar. At their outer ends these levers have verticaltongues 34 for engaging through slots 35 provided in the ends of theangle pieces 31, and at their inner ends the levers have slots 36 and 37respectively for receiving a staple 38 extending from a plate 39, thestaple being inserted through the slot 40 in the bar 16 and through theslots 36 and 37 of the levers to receive a pad-lock 41. To release theguard from the sash the padlock is removed and the staple withdrawn, andthe latch levers then rotated to withdraw their tongues 34 from thefittings 31., and the bar 16 can be withdrawn from the fittings, andthen when the guard is tilted inwardly the ends 24 can be withdrawn fromthe loops 29 of the sill fittings. To prevent removal of the ends 24from the loops when the guard is in service, the plates 27 have theirouter ends deflected upwardly to form guard walls 42. Also to preventoutsiders from removing the screws 28 and thereby releasing the plates27, I provide guard plates 4-3 for the fitting plates 27, these guardplates having the central openings 44 for receiving the loops and havingears 45 by means of which they may be secured to the sill by screws 46.When in place these guard plates will cover up the screws 28 of the sillplates 27. The screws 46 could, of course, be removed from the outsidebut the ends 24 of the guard will still hold the guard plate over theplates 27 to protect the screws 28. The screws 46 are provided merely todow.

hold the guard plates in place to prevent accidental removal thereofwhen the guard is removed from the window. WVith the arrangementdescribed the guard can readily be inserted and secured to then followthe movements of the lower sash or can be readily removed, and afterbeing secured it will be impossible for outsiders to enter or to removethe guard. Preferably the fittings 31 are secured to the lower sashsides a distance upwardly from the bottom of the window so that thewindow sash will prevent an outsider from getting at the screws by whichthe fittings 31 are secured.

I also provide guard means for any opening left by the lowering of theupper win- As shown, a lazy tongs 47 has its lower links pivoted to ahasp 48 and its upper links pivoted to a plate 49 from which extends theL-shaped latch member 50 for hooking into the loop 51 formed on a plate52 secured in the groove 53 at the top of the window frame. A tongue 54extends from the top of the upper sash 13 to be received by the notch 55in the hasp 4-8, the tongue having the hole 56 for receiving the padlock57. Preferably, the lazy tongs are of such size as to limit the downwardmovement of the upper window so that an outsider cannot enter, or, aguard structure similar to that for the lower sash may be provided. Inorder to prevent an outsider from detaching the plate 52 a guard plate57 similar to the guard plate 43 may be provided to receive the loop 51and to cover the screws which hold the plate 52 in place.

As changes and modifications may be made which would still come withinthe scope of the invention, I do not desire to be limited to the exactconstruction and arrangement shown, and I claim the follow- 1.
